Summary
The article challenges the conventional narrative of IPv4 address exhaustion, arguing that the shortage is artificial due to hoarding by large organizations and speculators. It reveals a complex secondary market where IP addresses are leased, traded, and manipulated, creating a shadow economy. The piece explains how this system allows entities to obscure IP ownership, scrub usage history, and choose geographic appearance, enabling various legal and illegal activities. It details the mechanics of IP leasing markets, the role of brokers, and the implications for internet governance and security.
Key quotes
· 5 pulledThe IPv4 'exhaustion' is not real. The addresses got hoarded and the market devolved into a wild sub-leasing economy where anyone can choose where their IPs appear from, who owns them on paper, and scrub them clean of any history.
You've heard it a thousand times: we've run out of IPv4 addresses. ARIN, RIPE, APNIC — every Regional Internet Registry (RIR) will tell you their free pool is depleted. And technically, that's true. The RIRs have no more fresh allocations to hand out.
The real story is that the addresses didn't vanish — they just got hoarded. By large corporations, by speculators, by anyone who saw the writing on the wall and decided to sit on a /8 or a /16 like digital gold.
This secondary market has become a shadow economy, complete with brokers, arbitrage, and all the usual financial shenanigans. And like any unregulated market, it's ripe for abuse.
The most dangerous aspect of this system isn't the hoarding or the speculation — it's the ability to completely decouple an IP address from its history and its true owner.
